MACHINE-BELT BUCKLE.

Specification of Letters Patent.

Application filed August 30, 1916. Serial No. 117,761.

To all whom it may concern:

Be it known that I, CHAnnus H. Bun'r'r- Nnn, a citizen of the UnitedStates, residing at Cincinnati, in the county of Hamilton and State ofOhio, have invented new and useful Improvements in Machine-Belt Buckles,of which the following is a specification.

My invention relates to machine belt buckles, particularly buckles forautomobile fan belts.

It is frequently necessary, where endless belts cannot be employed, toprovide means on the ends of a belt whereby the same may be joined. Insuch buckles as have heretofore been provided, great accuracy insecuring the parts of the buckle to the ends of the belt is required, inorder that perfect alinement of the ends of the belt when assembled, maybe seoured. Even where such accuracy in placing the buckle parts uponthe ends of the belt is attained, slightly faulty construction in thebuckle may cause the belt ends to be out of alinement. If not in perfectalinement, the belt will not of course remain upon the pulley on whichit is intended to operate.

The object of said invention is to provide a belt buckle of simple andinexpensive de sign, and of such construction that when the two parts ofthe buckle are placed upon the ends of the belt and joined together, theends of said belt will be automatically brought into perfect alinement.

In the several figures of the drawings, like numerals indicate likeparts.

In the drawings:

Figure 1 is a plan of my new buckle.

Fig. 2 is a side elevation of the same secured to the ends of a belt.

Fig. 3 is a plan of one of the parts of said buckle.

The numerals 1 and 2 indicate the two leaves or parts of my new buckle.The same are constructed of thin metal and are provided withperforations 3 through Whichrivets l pass to attach the buckle parts tothe ends 5 of a machine belt. The part 1 of said buckle is provided witha curved opening 6, the forward end of which opening forms a hump 7.Integrally formed with the part 2 of the buckle is a hook 8. The saidhook 8 is of substantially the same width as the opening 6 and isarranged to contact tangentially when the buckle parts are assembledupon the hump 7 of said opening and to rock thereon.

The nature and operation of my invention will be apparent from theforegoing description to those skilled in the art. When the parts 1 and2 of the buckle have been secured to the belt ends and the hook 8secured in the opening 6, the ends of the belt are brought into perfectalinement by the rocking of the hook 8 upon the hump 7 of the bucklepart 1 as above set forth.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:

A buckle for machine belts comprising two leaves, one of said leavesbeing provided with an opening and a hump in said opening, a hook on theother leaf, said hook being adapted to contact tangentially upon saidhump and to rock laterally thereon, substantially as and for the purposedescribed.
